Like what? I am fairly familiar with his work, could you point out what you found problematic? Peterson talks mainly about personal responsibility as the only way to meaning in a life that is mostly suffering. Clearly this young man was influenced by that message.
I find objectionable his “slippery slope” argument about pronouns and his calls for silencing disciplines with which he disagrees.
I understand the slippery slope reference,but which disciplines are you referring to?
He’s called for some disciplines (e.g. women’s studies, anthropology) to be boycotted by students and ultimately removed.
